機械加工是指通過一種機械設(shè)備對工件的外形尺寸或性能進行改變的過程。按加工方式上的差別可分為切削加工和壓力加工。

生產(chǎn)類型通常分為三類：

1．單件生產(chǎn)：單個地生產(chǎn)不同結(jié)構(gòu)和不同尺寸的產(chǎn)品，并且很少重復(fù)。

2．批量生產(chǎn)：一年中分批地制造相同的產(chǎn)品，制造過程有一定的重復(fù)性。

3．大批量生產(chǎn)：產(chǎn)品的制造數(shù)量很大，大多數(shù)工作地點經(jīng)常是重復(fù)進行某一個零件的某一道工序的加工。

Machining refers to the process of changing the shape size or performance of the workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting and pressure processing.
Production types are usually divided into three categories:
1. Single-piece production: individual production of products of different structures and sizes, and rarely repeated.
2. Mass production: The same products are manufactured in batches throughout the year and the manufacturing process is somewhat repetitive.

3. Mass production: The product is manufactured in large quantities and most duty stations often repeat the processing of a particular part.
